IMPROVEMENT IN HEATING RAILROAD-CARS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, ROBERT A. CHESEBROUGII, of 126 Maiden Lane, New York, in the county and State of New York, have invented a new and useful Improvement in Heating Railroad-Cars; and I do hereby declare that the following is a full, 'clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification, in which drawing I Figure 1 represents a longitudinal vertical section thereof.

Figure 2 is a transverse section of the same. I

Figure 3 is alongitudinal section ofa modification of the same Figures 4 and 5 are sections of still another modification.

Similar letters indicate corresponding parts. I

This invention consists in the arrangement of steam-pipes, with suitable registers or stop-valves, in a train of railroadcars, in such a manner that live steam, directly from the boiler, or the exhaust-steam from the engine, can be passed through said pipes, and that the heat in each car can be regulated without interrupting the passage of the'stcam through the succeeding car or cars; The several steam-pipes are connected together by flexible pipes, and they pass through the cars, eitherin jackets, the interior of which can be made to communicate with the interior or with the exterior of the 'car, or two sets ofpipes may be applied, one outside and one inside of each car, the pipe on eachcar being connected together by branch pipes, so that the steam can be made to pass either through the pipe or pipes in the cars, or through the pipe or pipes outside the'cars, or

through the inside pipe in one and the outside pipe in the succeeding car, at the will of the passengers or of the conductor.

A represents a railroad-car, constructed in the usual or in any desirable manner. Through this car extend two pipes, a b, which connect with-similar pipes, extending through the next preceding and the next succeeding cars, and through these, with the steam-space of the boiler, or with the exhaust-pipe or pipes of the engine. The pipes, at b oi' the last car in the train are connected at their ends by a pipe, 0, and'the connections between the pipes of the adjoining cars are edected .by flexiblepipe s d, which do not interfere with the motions of the cars, and which can be readily disconnected and connected as occasion may require. The pipes ab are enclosed in jackets, ef, which are situated on the sides of the car, as shownjn figs. 1 and 2, or one such jacket may b0 used, as shown in figs. d and 5. The jackets efare provided each with, two sets of registers, g it, one set to open into the interior of the car, and the othc/r' set to open to the exterior-thereof. By opening the outside registers 71. and closing the inside registers g, all the heat radiating from the steam-pipes is allowed to escape in the open atinosphere, but by closing the outside registers and opening the inside registers, the heatradiating from the steam-pipespasses'into the car and raises the temperature therein. I

If the steam-pipes, are enclosed in round jackets, as shown in figs.'4 and 5, the registers may be made'in the form of sleeves,.g which turn on thejacket, and serve to open and close the apertures ij in said jackets, the apertures i leading to the inside and the apertures to the outside of thecar.

The jackets and registers may, however, he dispensed with, if the steam-pipes a b are arranged as shown in fig. 3. In this ease the pipe at is inside, and the pipe 6 outside the car, both being connected by branch pipes 7c; and said pipesare provided with stop-cocks Zm, so that by closing the cocks Z and opening the cocks m, the steam is made to pass through the inside pipes a, and the temperature in the car is increased, but by closing the cocks at and opening the cooks Z, the steam i's'made to pass through the outside pipe 6, and no increase of temperature takes place in the interior of the ear.

If it is desired to use the steam after heating the cars, eachcar will contain two pipes, or two sets of pipes, one on each side, (figi 1,) so that the steam, passing out in one direction, can be inade to return in the opposite direction, and the steam, after having passed through all the cars,'can be thrown into the smoke'stack to increase the draught, or it can he conducted into the water-reservoir of the tender, to heat the feed-water; orit may be used for both these, purposes. It is'obvious that the pipes a b may be situated at the top or at the bottom of the car, as may in practice he found to he most advantageous.

I do not claim broadly as my invention the use of either exhaust or 1iv'e steain What I claim as new, and desire to secure by Letters Patent, is-

1. The arrangement, in a. railroad-car, of steam-pipes a 6,-in combination with registers whereby the heat can either be thrown into or to the outside of the car, steam in thesucceeding car or cars, substantial ly as set forth.

2. The arrangement, with a railroad-car, of inside and outside size for heating-cars, but

9 h, or equivalents, without interrupting the action of the am-pipcs, when coirstx ucted nndepplied substintiallyas described in fig. 3, for heating purposes.
